• Shift+Right - next or previous tab in tab-set

How-To

Where I find a build number of the application?

See web.xml

Technical Info

Dependency

• Apache Tomcat
• CCT - command line tool
• CleverGWT
• User Management
• Lexicon (SQLite)
• Application data storage (MySQL, MS-SQL)
• Temporary directory (only for tests)
• Directory with configuration file config.yaml

# /etc/sudoers
tomcat ALL = (root) NOPASSWD: /usr/local/plc/bin/cct *

Authentication

• CLEVER User Management (centrální správa uživatelů a jejich práv)
• Tomcat (internal, LDAP, ...)

Aplikace mimoto poskytuje pro testovací účel vlasní integrovanou autentifikaci pro tři na pevno dané uživatele: cadmin, john a steve.

Authorization

Server Side

Práva přiřazovaná uživateli jsou rozlišována na následující úrovni:

• user - aktuálně přihlášený uživatel
• method - identifikace požadované funkce rozhraní serveru
• action - minimální požadované oprávnění (Read/Write = 2, Read = 1)
• value - parametr funkce rozhraní určený k prověření jeho hodnoty (speciální hodnoty: "--" pro NULL a znak pro cokoliv " * ")
• position - pozice parametru ve funkci

Položkou value může být libovolný objekt jehož hodnotu vyhodnocuje (převádí na string) server.

Funkce, které mají být zahrnuty do autorizačního procesu se anotují ve třídě RemoteService. Např.:

 @Secure(action = Secure.Action.READ_WRITE)
 public void generateDiffView(@Secure.Check String configName, AsyncCallback<String> callback);

Client Side

Not implemented yet. (Jedná se o disable/enable tlačítek GUI)

Deploy

• See build.xml
• web.xml - setup path where to find config.yaml <param-name>configuration</param-name>

Test

• Check List
• Bug List
